It's an enthusiastic drama , at first sight it's looked boring and silly but no it's one of the best drama you can binge watch it , there were a lot of things going on and it's really enjoyable drama that for sure you are going to enjoy every episode, but I'd like to talk about characters in the drama more than events ,because the two main characters besides the other two cops characters are so good , it's started with just normal characters but over time the characters develops their own personality , you can see them at first how coward and distracted they are and impatient and of course no one wants to sacrifices them self for the case or want to think harder but over time we can see the male characters and how he become so brave and so smart and how he started to take action in saving the situation and protecting the female main characters,
on the other hand , we can see the female characters and how she devolved her personality from being an impatient person to an amazing and focused person who is trying so hard to save a lot of people life , how she and the male characters trying so hard to find the truth and solve everything while fighting with their own emotion of running a way from the scene , and focusing in every corner ,knowing they can get hurt .

I recommend watching this drama and of course I'm going to re watch it again.
